How This Is Us Will Handle Its Big Deja Episode

Isaac Aptaker said the Deja episode will explore how she ended up in foster care to begin with, and fans will also get a little bit more insight behind characters like Debra Jo Rupp's social worker Linda. As well, we'll get a chance to witness the relationship between Deja and her mother Shauna, which presumably means This Is Us will finally reveal what Beth and Randall saw in Deja's case file, and the episode could explore the origins behind some of the more worrisome habits she exhibited earlier in Season 2.
Unfortunately, Aptaker said nothing about the upcoming episode's story resolving the big present-day cliffhanger, where she was found by Beth and Randall sleeping in a car with her mother. One would hope there's some sort of conclusion to that soon, as it'd be a cruel thing to show all this backstory and then spend the Season 2 finale at Kate's wedding without anyone knowing what's going to happen with Deja until Season 3!
